Francois, that is horrific.
Have all the sh*t-for-brains who infest the "staff" side of the counter at Walmart had a collective frontal lobotomy? For my money, doing something like that should be punishable by an instant, heavy-duty and prolonged kicking. Getting $3 back doesn't begin to get close to what's required.
What is the point of putting someone behind the counter that can't even see there aren't spaces where the frames normally end and, worse still, carries on cutting despite the lack of spaces? Can you imagine what it must be like on the inside of that person's head? I can't. It's too scary to contemplate.
I just hope that you'll be able to replicate the images shot - closely, if not identically. Really sorry for your loss.
